Metallics JSBN38 – Frequently Asked Questions

1) Will Metallics JSBN38 hex nuts thread onto a standard 3/8-16 bolt or rod?
Yes. The JSBN38 is a 3/8 inch nut cut at 16 threads per inch to ANSI/ASME B1.1, which is the standard UNC coarse pitch for 3/8 inch fasteners. It will run on any 3/8-16 UNC bolt, stud, or threaded rod. It will not fit 3/8-24 fine thread.
2) Why use silicon bronze nuts instead of galvanized or stainless for electrical grounding work?
Silicon bronze is the material called for where you are fastening to bronze or copper grounding hardware: it resists corrosion in wet and buried conditions and avoids the dissimilar-metal reaction you get putting a steel nut on a copper or bronze ground rod clamp or lug. The JSBN38 is solid silicon bronze throughout, not a plated steel nut, so there is no coating to wear through at the threads.
3) Do Metallics JSBN38 nuts meet a dimensional spec I can put on a submittal?
They are made to ASME B18.2.2, the dimensional standard for square and hex nuts, with threads to ANSI/ASME B1.1. Those are the two citations a spec writer or inspector usually wants on a nut, and both appear on the Metallics JSBN series record.
4) How many nuts come in a jar and can I buy fewer than 50?
The JSBN38 ships as a jar of 50 pieces, and 50 each is the order minimum, so it is sold by the full jar rather than loose by the piece. The filled jar weighs 0.91 lbs.
5) Can I torque these down hard like a Grade 5 steel nut?
No. Silicon bronze is softer than medium-carbon steel, so a bronze nut should be run to a lower torque than a Grade 5 or Grade 8 steel nut of the same 3/8-16 size, and it should be mated to a bronze or copper-alloy bolt rather than used to hold a high-strength steel joint. Use it where corrosion resistance and conductivity matter, not where clamp load is the governing requirement.
6) Are these bronze hex nuts only for electrical, or can I use them on plumbing and HVAC jobs?
Metallics lists the JSBN silicon bronze hex nuts for electrical, plumbing, and heating and air conditioning work. The same corrosion resistance that suits them to grounding and panel hardware makes them usable on damp mechanical-room and piping support assemblies, anywhere a steel nut would rust out.
7) Is the Metallics JSBN38 acceptable on a federally funded or Buy American project?
The JSBN38 record carries both an ARRA compliance and a Buy American compliance flag, with country of origin shown as multiple. For a job with a strict domestic-content clause, treat the origin as multi-source and verify the specific lot documentation your spec requires.
